Find an RV show near you, it's worth a few hour drive if you have to... There are hundreds of options for you out there.
Choices are overwhelming.... Sometimes just finding a friendly local dealer, that has a brand you like, can be a blessing. It helps you focus your search.
Things that are a must for me: (but may be different for you)
1. Slide. Really opens up space. Worth every penny.
2. Outdoor kitchen. When I'm camping, I'm outdoors. An outside kitchen is a great way to be outdoors, with the convenience of indoor appliances.
3. High ceilings. I'm taller, and low ceilings make a small TT feel even smaller.
Just a few things to think about. Really you'll never know what you want or need until you're out there camping.
For a brand suggestion, look at the Outback Terrain line. I have a 260trs, they're unique units with some nice features. They're worth a look.
